Bill and his wife Peggy joined Amway in 1970, ten years after the company began, and built one of the largest Amway businesses in the world. They reached Diamond level in 1973 and Crown Ambassador in 1996. In 2004 they were recognized as Founders Crown Ambassador, FAA 40, one of only 14 Amway distributorships in the world to have reached that level.

The Britts are downline of Founders Crown Ambassador Dexter Yager, and were an integral part of the success and expansion of the “Yager System” in the 70s and 80s. The Britt’s eventually founded their own business support company, Britt WorldWide which grew around the world, reaching great success particularly in India, where the Britt’s developed a second large Amway business, reaching Crown in 2009.

Their success was not without controversy however. Britt’s firebrand approach, with no apologies for mixing his strong evangelical Christian faith, political beliefs and business attracting devotion from many but criticism from others. In 2004 the Britt organisation was the focus of a Dateline NBC investigation into Quixtar (now Amway North America) and several of his downline distributors were disciplined by Amway as a result.
